This study examines the social meaning of the CosPlay, the growth potential of CosPlay culture and its effect on the related industry through the perspectives and language of the youths who enjoy CosPlay, based on the ethnographic research. Also, this study presents a comparative description of Korea and Japan CosPlay culture by the ethnographic methodology whose purpose is to define relationship of cause and effect with phenomenon. For further step, this study plans to emphasize the need to link culture, clothes and related industry in order to create a cultural environment where diversity co-exists. CosPlay is the mania culture of Japan that emulated the Halloween party of the West and that developed the party into a unique form. In Korea, this practice was accepted for the first time among a handful of youths, starting from the 1990s, after which, it was introduced to the masses while holding CosPlay related events. While CosPlay is succeeded as an industry in Japan, CosPlay in Korea is considered childish play due to the Korean culture of considering cartoon as a childish and low class genre which is enjoyed by youths. CosPlay in Korea faces the following changes: aging of the members who comprised the CosPlay culture at the initial stage; population increase, centered on middle and high school students; interest of the government and the businesses that wish to produce economic wealth by organizing CosPlay events into events for youths; and changes in the environment that comprised the surrounding of the CosPlay culture. CosPlay is an honest play that demonstrates one's effort on the stage through performance. Moreover, most of the middle and high school students who comprise the CosPlay culture demonstrate similar characteristics as mania type of people when it came to the reason that they enjoy CosPlay. However, they did not consider CosPlay culture as an important aspect of their lives. Instead, most of them said that they participate to relieve stress. Thus, they have the potential to move onto another form of youth culture that may appear more attractive to them. To them, it is not the CosPlay culture that is important, but the fact that CosPlay provides a forum where they can freely engage in play.

Morphology of methane/propane clathrate hydrate crystal was investigated under different undercooling conditions. After the water pressurized with compound guest gas was fully saturated by agitation, medium within the vessel was rapidly undercooled and maintained at the constant temperature while the visual observations using microscope revealed detailed features of subsequent crystal nucleation, migration, growth and interference occurring within liquid pool. The growth of hydrate was always initiated with film formations at the bounding surface between bulk gas and liquid regions under all tested experimental conditions. Then a number of small crystals ascended, some of which settled beneath the hydrate film. When undercooling was relatively small, some of the settled crystals slowly grew into faceted columns. As the undercooling increased, the downward growth of crystals underneath the hydrate film became dendritic and occurred with greater rate and with finer arm spacing. The shapes of the floating crystals within liquid pool were diverse and included octahedron and triangular or hexagonal platelet. When the undercooling was small, the octahedral crystals were found dominant. As the undercooling increased, the shape of the floating crystals also became dendritic. The detailed growth characteristics of floating crystals are reported focused on the influences caused by undercooling and memory effect.

In this study, the effect of particle size on the combustion characteristics of pulverized sub-bituminous coal was experimentally investigated. A laminar-flow-entrained reactor was designed and implemented to realize the desired heating ratio and temperature corresponding to the combustion atmosphere of a pulverized-coal-fueled furnace. The flame length and structure of burning particles according to different sizes were investigated. Coal combustion processes were clearly distinguished by direct visual observation of the flame structure. The onset point of volatile ignition is greatly affected by changes in the particle size, and the burning time of the volatiles is least affected by changes in the particle size. The length and instability of char flame also increase with the increase of the particle size. However, the char consumption rate within the residential time remains nearly constant.

This study was designed to evaluate the pain control effect by morphine injection to masticatory muscle pain patients. Patients with masticatory muscle pain visited the Department of Oral Medicine, Kyung Hee University Dental Hospital were recruited to this study and diagnosed by RDC/TMD. Experimental group were divided into three group; saline injection group(n=10), lidocaine injection group(n=10) and morphine injection group(n=10). Evaluation list was the subjective pain evaluation(visual analogue scale, Mc Gill pain questionnaire, pain drawing) and the objective pain evaluation(pressure pain threshold, pressure pain tolerance) and evaluation time was injection before, after 10min, 30min, 60min and then it was analyzed statistically. The results were as follows : 1. The subjective pain evaluation and the objective pain evaluation were significantly different statistically in within subject effects(p<0.001). 2. The subjective pain drawing evaluation(p<0.001) were significantly different statistically in between subject effects. 3. The objective pressure pain threshold evaluation(p=0.025) were significantly different statistically in between subject effects. 4. The morphine injection group(p=0.001) were more significantly different than the saline injection group statistically in the subject pain drawing evaluation. Therefore, it was considered that the morphine injection was effective to pain control for masticatory muscle pain patients within 60 minute.

The current study examined how different level of self-constol and construal level influences game users' game addiction. Also we explored the interaction effect between the individual's self-control and construal level on game addiction. To answer the research questions, we conducted an online survey and total 918 participants were selected for the final analysis. According to the results, users with low level of self-control and low-level construal showed higher level of game addiction. In addition, we found a significant interaction effect between self-control and construal-level on game addiction. In high self-control group, game addiction level was low regardless of level of self-construal. However, in low self-control group, the level of construal-level affected game addiction. We found that construal-level played an important mediating variable. These findings suggest a noble insight for autonomous control in alleviatinggame addiction by changing one's level of self-control and self-construal.

This study examined the effect of VT(Vibration Training) on the symptoms of DOMS (Delayed-Onset Muscle Soreness) before induced by eccentric exercise of the left leg triceps surae. Twenty one healthy adult men and women who had not participated in a regular exercise program for the lower extremities were assigned to one of two experimental groups: vibration training group, Control group. We measured the VAS(Visual Analogue Scale), ankle plantar flexor strength, triceps surae circumference, CK(Creatine Kinase) before and after exercise and 24, 48 and 72 hours after eccentric exercise. After inducing DOMS, VAS showed significant differences between groups at a point of time 48 hours, and showed significant differences within groups in accordance with the time of measurement(p<.05). Plantar flexor strength of groups with VT did not show significant difference between groups but, showed significant differences within groups in accordance with the time of measurement(p<.05). Triceps surae circumference of groups with VT did not show significant difference between groups but, showed significant differences within groups in accordance with the time of measurement(p<.05). CK of groups with VT did not show significant difference between groups but, showed significant differences within groups in accordance with the time of measurement(p<.05). As a result of the study, VT prior to eccentric exercise is effective to inhibit pain. So, this method can be suggested to prevent DOMS in doing an unfamiliar activites.

These studies were designed to determine the effect of hydroalcoholic gel system (lower alkanol concentration: 40-60%) compared to general hydrogel system (lower alkanol concentration: 10-35%) on transdermal delivery of piroxicam and its anti-inflammatory activity. Piroxicam was incorporated into a hydroalcoholic gel and a hydrogel containing polymers, solvents, and cosolvents. The pH of gel was about 6.3-7.3 and the solvent mixtures were composed of water and various concentrations of ethanol (35, 40, 50, and 60%). For the in vitro study, the skin permeation of piroxicam from the gel formulations was investigated using Franz modified diffusion cells fitted with hairless mouse skin. For the in vivo study, the anti-inflammatory activity of hydroalcoholic gel was compared to other commercial products (piroxicam hydrogel and ketoprofen hydrogel) in rat and human. The anti-inflammatory activity was determined using carrageenan induced foot edema model in rat. For the clinical study, it was evaluated from determining efficacy and acceptability with 98 patients suffering from musculoskeletal pain. A novel piroxicam hydroalcoholic gel was successfully formulated in the range of 40-50% of ethanol as solvent, more than 10% of propylene glycol, 5% of $Transcutol^{\circledR}$ and 1 % of benzyl alcohol. The skin permeation of piroxicam using hydroalcoholic gel system was greater than that of general hydrogel system $(flux\;:\;139.1-148.2\;{\mu}g/cm^2/hr\;vs.43.0-84.5 {\mu}g/cm^2/hr)$ in vitro. In carrageenan-induced edema model, the anti-inflammatory activity of hydroalcoholic gel was better than that of piroxicam hydrogel for edema inhibition (75.1 % vs. 62.9%, p
